【问题描述】：
我正在尝试安装一个名为 stn 的 luarocks 包。官方的安装方式是运行：
luarocks install https://raw.githubusercontent.com/qassemoquab/stnbhwd/master/stnbhwd-scm-1.rockspec
但这给了我不幸的，加剧的错误：
nvcc fatal : Value 'sm_20' is not defined for option 'gpu-architecture'
据我所知，解决此问题的唯一方法是手动更改 CMakeLists.txt 文件：
IF (CUDA_FOUND)
LIST(APPEND CUDA_NVCC_FLAGS "-arch=sm_20")
收件人：
IF (CUDA_FOUND)
LIST(APPEND CUDA_NVCC_FLAGS "-arch=sm_30")
这意味着我必须将 repo 克隆到本地文件中，更改 CMakeLists 文件，然后 luarock 制作它。 （作为免责声明，为了做到这一点，我不得不chown我的整个用户，因为无论出于何种原因，luarocks 似乎都没有目录写入权限。我到底有多糟糕？）。
所以，我能够通过 cding 进入主目录并安装 .rockspec 文件：
luarocks make stnbhwd-scm-1.rockspec
这给了我这个输出：
$ luarocks make stnbhwd-scm-1.rockspec
cmake -E make_directory build && cd build && cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH="/home/tex/torch/install/bin/.." -DCMAKE_INSTALL_PREFIX="/home/tex/torch/install/lib/luarocks/rocks/stnbhwd/scm-1" && make

注意“警告”标志。我不知道为什么会这样，但我认为它对安装有一些明显的影响，因为当我加载 stn 时...：

sigh 有人知道解决办法吗？有解决方法吗？ LuaRocks 仍然适用于安装包，但也许我在安装本地包时做错了。有没有办法安装 stn 包，同时在安装之前更改 cmake 文件（而不是下载包并手动更改它）？我对此表示怀疑，但是... :(
编辑：任何阅读本文的人，请参考this page。我基本上说搞砸了，并将编辑后的 repo 上传到我自己的 github 页面上。现在，我面临一个不同的错误。
